What Rain Capital does
Rain Capital is a Palo Alto-based, privately-held venture capital firm founded in 2017 that invests at Pre-seed, Seed, and Series A stages in companies building infrastructure for the AI-native enterprise. The firm's stated thesis identifies AI, Cybersecurity, and Healthtech as three converging, compounding domains, and it employs an "expert-led, community-assisted sourcing" approach partnering with exceptional founders and top academic institutions.
The portfolio spans roughly thirteen disclosed companies across operational technology security (Claroty), cyber asset management (JupiterOne), identity and access (Elisity, Astrix Security - acquired by Cisco for ~$400M), supply chain security (Ox Security), AI security and runtime protection (Lakera - acquired, SPLX - acquired, Lema AI, Straiker AI, Fleak AI), data and confidential computing (Oasis Labs - acquired), and exposure management (runZero - acquired by Accenture in a ~$4.2B combined transaction). Recent co-investments include Manifold ($8M seed, AI Detection and Response for autonomous agents) alongside Costanoa Ventures, Cherry Ventures, and Modern Technical Fund, and Clario ($6M seed, enterprise data management) with Preface Ventures.
Rain Capital generates returns through traditional venture economics: equity investments in early-stage startups with exit realization via acquisition or IPO. The team is intentionally lean (1-10 employees) and the firm does not publicly disclose AUM, fund size, management fee structure, or LP composition. Distribution of capital occurs through direct equity investments led or co-led in funding rounds, supplemented by thought-leadership presence at industry events (RSAC Conference 2026) and recognition programs (Notable Capital's 2026 Rising in Cyber List).
